2.2 Engine Electronic Control Module(ECM)
u After the control system of the muti-point sequential ignition engine collects the position signal of the camshaft, it controls the ignition coil to fire in sequence.
u 12V,24V compatible
u The ignition time and ignition energy can be accurate via programming the Map.
u Equip high energy ignition coil for each cylinder
u Self-learn Function: ECW will self-correct the running parameter via temperature sensor, pressure sensor and throttle position signal.
u Industrial grade spark plug, high voltage wire
u Work Temp. :-20°to 85°
u Exhaust System
u Wet,Heat insulated exhaust manifold
u Industrial grade muffler
u Exhaust shock proof corrugated pipe
2.3. Lubricating System
